@EloquentPlatypus a video would be helpful if you have one. One thing to note is that you were against a heavy that may have pulled out a shield, that shield may not have been seen because you shot it very quickly. I use the heavy all the time and get occasions where I pull out my shield and it dissappears in a flash through damage but gives me just enough time to take out the opponent first. I barely see the shield I just know I activated it, it's possible my opponent doesn't even realise a shield has been activated.
That being having been said is one possibility but I also find in certain games where it feels like lag despite a lack of the normal symptoms such as stuttering etc, where it is as you describe, you shoot at an opponent your aim is on them yet the shots don't seem to connect and you die instead stratching your head. On some of these occasions I find they will die half a second later, and I will get the points for the kill which is what leads me to believe there is a slight lag or at least something mistimed about the way the game is processing the information. I'm sure more technical bods than me can explain. Usually if I have it happen repeatedly in the same game, I will leave and look for a new game where it normally resolves itself and combat registers hit markers as it should.
Btw the empty server thing is an issue for a lot of people.
